I I . GENERAL INFORMATION
VIBTransmitter VT1000 is a universal module for condition monitoring of rotating machinery
with constant and variable rotational speed.
The features of VT1000 are as follow:
ICP® (IEPE) standard accelerometer input,
4..20 mA output proportional to signal estimate,
vibration velocity or acceleration measurement,
calculation of RMS or PEAK values,
built-in connector for the AC voltage signal from the vibration sensor (10 Vpp),
DIN rail mounting.
The system is a perfect solution for automated protection systems of rotating machines. The
device can be integrated with the controller via the 4..20 mA current output. The 10 Vpp AC
voltage output allows to control the vibration level using a portable vibration analyzer.

IV. FRONT PANEL DESCRIPTION
Measurement chain diagnostics for IEPE sensor
Red LEDs – indicator of the sensor status:
open – open circuit or sensor failure
short – short circuit or sensor failure
Green LEDs:
indicator of the selected estimate: o RMS – RMS value of vibration signal o PEAK – maximum value of vibration signal (0-Peak)
indicator of the selected measured value: o acc – acceleration o vel – velocity
Scaled diode measurement level indicator.
V. INSTALLATION AND USAGE
V.1. MOUNTING
VIBTransmitter VT1000 module is designed for mounting on 35mm DIN rail in an upright
position. Figure 2 presents the 3 modules of VT1000 mounted on a DIN rail.

V.2. GALVANIC ISOLATION
VIBTransmitter VT1000 guarantees full galvanic isolation between power supply of the
module with the sensor and the current loop in the case of external supply of the 4..20 mA
current loop. Figure 3 presents the schematic block of above mentioned isolation.

V.3. ELECTRICAL CONNECTORS
Description of the connectors is presented on the Figure 4.

V.4. AC VOLTAGE OUTPUT
The usage of the voltage output of the module should be performed according to Figure 6.

V.5. ACTIVATION
After connecting the power, the VT1000 module enters into testing procedure. Subsequently
all LEDs will flash for a short period of time. If everything is operating properly, then LED is
pulsing with a frequency of approximately 1 Hz. Once the testing procedure is over, the
device is ready to operate. If an error of a sensor circuit is detected, then corresponding LED
will lit.
VI. MEASUREMENT PARAMETER CONFIGURATION
Measurement parameter configuration is set by proper set-up of configuration switches
SW1 and SW2. Description of switches SW1 and SW2 is presented in the following table and
Figure 7:

Figure 7 » Functions of configuration switches
Example:
Monitoring of the RMS of the vibration signal velocity, using 3 Hz high pass filter and 10 KHz
low pass filter, for 100 mm/s range and internal power loop. The following configuration of
the switches must be set:
SW1 SW2
OFF ON OFF OFF OFF ON OFF ON OFF OFF OFF ON ON OFF
1 2 3 4 5 6 7 8 1 2 3 4 5 6
WARNING!
The set-up of the switches configuration should be done on a switched off device. If the
set-up was done on an operating module, it needs to be restarted in order to activate the
new configuration.
